It is better for you to understand the problems than to answer them for you. With these, you combine the like terms, which means the numbers that are in front of each of the same letters (if there is no number you assume the number is 1) and make sure to pay attention to a "+" or "-". For example:

x-2x+y-y

Add up all the values for x, in other words, the 1 (from x) and the -2 (from -2x), which gives you 1+-2=-1; so the final value for the x's is -x. Then add up the values for y, 1+-1=0; so the final value for the y's is 0y (or just 0). So you end up with:

x-2x+y-y = -x

I have a GED and am doing just fine in life. I'm nearly complete with an Associates degree and after that have had a number of colleges interested in myself to continue my education. By the way, I have a 3.8 GPA, so I did not get a GED because I was too "stupid" to finish high school. Its just as good as a diploma.

Jose, go to http://www.quickmath.com/ and type in your problems there. It looks like on 4&5 you might want to combine terms,cant tell if thats a "2" or power of two.

Make up your man or woman questions to respond to or print out some greater good math worksheets which you would be able to artwork on interior the lesson and then ask your instructor to income them, or perhaps ask your instructor to grant you some greater good stuff to artwork directly to improve your training. I hate maths to be honest so this may well be something that i might under no circumstances ever ask to do greater of lol.

Do you really expect to get anywhere in life with a GED?

Get a Diploma, You will get a lot further in life..
Im not being rude, but all the friends i have work fast food,
plumbing...

and if you ever want to get a degree, you have to go back and get your HS diploma.

Its not worth the hassle.
